Suitable for use with a wide range of rigs and lead sizes. When assembled the components provide a safe streamlined bolt rig that is completly fish safe. The whole principle of the rig is the swivel is fixed into place via a small plug held in the lead clip. This ensures that if a fish becomes snagged the lead will be able to break free as the swivel cant move. Kit contains 10 lead clips, 10 tail rubbers and 10 swivel plugs. Available to be compatible with either size 9 swivels, size 10 swivels or size 11 swivels.
